Hall Effect
Category : JEE Main & Advanced
The Phenomenon of producing a transverse emf in a current carrying conductor on applying a magnetic field perpendicular to the direction of the current is called Hall effect.
Hall effect helps us to know the nature and number of charge carriers in a conductor.
Consider a conductor having electrons as current carriers. The electrons move with drift velocity \[\overrightarrow{v\,}\] opposite to the direction of flow of current
Force acting on electron \[{{F}_{m}}=-e(\overrightarrow{v\,}\times \overrightarrow{B}).\] This force acts along x-axis and hence electrons will move towards face (2) and it becomes negatively charged.
